“…In recent years, a typical metal-free polymeric graphitic-like carbon nitride (g-C 3 N 4 ) made of earth abundant elements has attracted considerable attention because of its visible light photocatalytic response, specific electronic properties, inexpensive, chemical inertness, thermal stability and nontoxicity [11][12][13][14]. Wang et al firstly used g-C 3 N 4 as visible-light-driven photocatalyst to produce hydrogen and oxygen by water splitting with visible light irridation [15].…”

“…Photocatalytic hydrogen production through water splitting by using solar energy has been considered as an alternative environmentally benign way, but it is limited to develop highly active and stable photocatalysts at low cost. So far, various photocatalysts have been developed for H 2 production, for instance, metal oxide (TiO 2 [5][6][7], NiO [8], CuO [9]), metal sulfide (CdS [10], CuS [11], NiS [12], MoS [13,14]), and nitride semiconductors (C 3 N 4 ) [15][16][17][18][19][20][21][22]. Recently, Yu and coworkers have made a systematic analysis of the heterojunction photocatalysts, which provides an important reference for the subsequent photocatalytic research [23].…”

The application of metal-organic framework (MOF) in the field of photocatalysis is limited, because of its unstable chemical properties and failure to respond in visible light. Herein, the Pd/MOF catalysts were prepared by impregnation reduction. It is important that we have reasonably constructed the dye-sensitized system of Pd/MOF and successfully extended the application of MOF to the visible range. It exhibited maximal photocatalytic activity (9.43 mmol/g) under visible-light irradiation (λ ≥ 420 nm) with eosin Y as a photo-sensitizer, which was enhanced twice the order of magnitude compared with the pure MOF (0.03 mmol/g). The activation process with an exchangeable guest solvent produced the Zr-MOF with the high surface area and the high stability, which provide a great electronic transmission capacity. The Pd nanoparticles provide an electronic outlet, and the dye broadens the spectral absorption range. The synergistic effect of the various components contributes to the high hydrogen production activity. This work provides a reference for the application of MOF in the field of photocatalysis.

“…However, the photocatalytic efficiency of g-C 3 N 4 semiconductors is relatively low and still far from the level required for real applications, mainly owing to the small surface area values and high recombination rate of photogenerated electron-hole pairs [5][6][7][8]. As a result, many efforts have been devoted to modify synthetic procedures toward g-C 3 N 4 to gain an efficient photocatalytic system, such as doping with metal oxides or nonmetal elements [9][10][11][12][13], construction of porous or hierarchical nanostructures [14][15][16], and combining other semiconductors with suitable band structures [17][18][19][20][21][22].…”

a b s t r a c tIn this study, a series of porous graphitic carbon nitride (g-C 3 N 4 ) materials were fabricated through a direct pyrolysis of protonated melamine by nitric acid solution. These as-prepared porous samples were characterized by a collection of analytical techniques. It was found that a proper concentration of nitric acid solution involved facilitated to generate samples in tube-like morphology with numerous pores, identified with X-ray diffraction patterns, FT-IR spectra, SEM, TEM, and BET measurements. These g-C 3 N 4 samples were subjected to photocatalytic degradation of dye Rhodamine B (RhB) in aqueous under visible-light irradiation. Under identical conditions, those porous g-C 3 N 4 samples showed significantly improved catalytic performance in comparison with the sample prepared without the introduction of nitric acid. In particularly, the best candidate, sample M1:1, showed an apparent reaction rate nearly 6.2 times that of the unmodified counterpart. The enhancement of photocatalytic performance could be attributed to the favorable porous structure with the enlarged specific surface area and the suitable electronic structure as well. In addition, ESR measurements were conducted for the sake of proposing a photocatalytic degradation mechanism.
